摘要: 基于Davies的乳化理论,推导了辛烯基琥珀酸淀粉钠(SSOS)的亲水一亲油平衡(HLB)值,研究了SSOS的乳化性质和流变性质.结果表明:不同取代度SSOS的HLB值都大于10,SSOS为亲水性乳化剂;SSOS具有较好的乳化能力,能稳定水包油型乳浊液,其乳化能力随着DE值提高而增强,但乳化稳定性有所降低;SSOS在高浓度下具有较低的粘度,且随着剪切速率的升高粘度有所降低.

Abstract:

The hydrophile-lipophile balance(HLB)value of starch sodium octenylsuccinate(SSOS)was calculat-ed based on Davies’emulsification theory.and the emulsification and’rheology properties of SSOS were then inves-tigated.The results indicate that all SSOS with different degrees of substitution have HLB values more than 1 0,pro-ving SSOS to be categorized as a hydrophile type emulsifier,that SSOS is of excellent emulsification capability and
can be used to stabilize oil/water type emulsion,that the emulsification capability of SSOS improves with the in-crease of dextrose equivalent,while the emulsification stab ility decreases a little,and that the viscosity of SSOS is relativelv lOW even at high concentration.and slightly decreases with the increase of shear rate.
